To obtain thewind load andwind-induced responses of theChongqingMarriott International
Conference Center Building, a tall steel structure building with a height of 303 m and the first
frequency of0. 123 4 Hz, to evaluate its living comfortableness and safety, a wind-tunnelmodel test
was carried outto simulate naturalwind in the turbulentboundary layeron the site of the building. The
distribution ofwind pressure on every surface of the buildingwasmeasured by a staticmode,l and the
static wind load was calculated. The wind-induced responses, including displacemen,t acceleration
and angular velocity responses, were measured by an aeroelastic mode,l and the dynamic wind load
was gained. The effects of its surrounding buildings and structureswere discussed. The result shows
that the surrounding buildings have great effects on the wind load, no galloping will occur for the
design velocity, the acceleration and angular velocity of the building top are smaller than their
allowances and the living comfortability of the buildingmeets the related national code.
